Technical Field

The utility model belongs to the lubricated field of gear specifically is a lubricated gear.

Background

Gears are common parts in transmission mechanisms, and ideally, a layer of oil film exists on meshing surfaces of gear teeth of two gears which are meshed with each other. If the lubrication is not carried out in time, the tooth surfaces of the two gears are in direct contact in the transmission process to generate hard friction, so that the tooth surface friction force is larger in the transmission process, and the noise caused by the transmission is larger. And after long-time use, the gear meshing surface is seriously abraded, and the transmission of the two gears is influenced. If manual lubrication is carried out, the manual lubrication can be carried out only regularly and quantitatively, continuous lubrication cannot be carried out, and the lubrication effect cannot be well guaranteed.

The purpose of the utility model is realized with the following mode: the utility model provides a lubricated gear, includes the gear body, and the gear body has axially extended centre bore and a plurality of teeth of a cogwheel that circumference distributes, the teeth of a cogwheel divide into the oil absorption tooth that goes out that has the oil-out and paste and be equipped with the oil absorption cotton, goes out oil tooth and oil absorption tooth circumferential spacing range and is equipped with a plurality of oil-outs on the gear body, is located the meshing face that goes out oil tooth one side, and the intercommunication has the oil guide passageway between oil-out and the centre bore, and oil-out department installs extrusion oil valve.

The extrusion oil outlet valve is in threaded connection with an oil outlet, the extrusion oil outlet valve comprises a stud with threads, a front wide stepped hole and a rear narrow stepped hole are arranged in the middle of the stud, a steel ball and a spring are arranged at the wide diameter of the stepped hole, the diameter of the steel ball is larger than a diameter locking port at the front end of the stepped hole, the front end of the steel ball is abutted against the diameter locking port, the tail end of the steel ball is abutted against the spring, two mounting holes are formed in the front end face of the stud, an annular groove is formed in the outer side face of the front end of the stud. When the double-screw bolt is installed, tweezers or a pair of sharp-nosed pliers can be inserted into the installation hole of the double-screw bolt, and the extrusion oil outlet valve is installed at the oil outlet. The sealing gasket is used for preventing lubricating oil from leaking and escaping.

Preferably, the oil absorbing cotton is a nano sponge.

Preferably, the oil absorption cotton is attached to the meshing surfaces on the two sides of the oil absorption teeth.

Preferably, the oil absorption cotton and the oil outlet are positioned on the same side of the gear teeth.

When the two gears are in meshing transmission, when the two gears are meshed with a meshing surface with an oil outlet, the steel balls in the oil outlet valve are extruded, the steel balls extrude the spring, the oil outlet is opened, and lubricating oil in the oil guide channel flows out to the oil outlet to lubricate the whole tooth surface. The gear teeth which are not in a meshing state have steel balls which close the oil outlet under the action of the spring, and lubricating oil cannot leak out. When the gear is meshed with the meshing surface with the nano sponge, if excessive lubricating oil flows out of the last meshing surface, the nano sponge can absorb the excessive lubricating oil; if the lubricating oil flowing out of the last meshing surface is too little, the lubricating oil absorbed in the nano sponge can be smeared on the meshing surface, and the lubricating effect is improved.

The utility model discloses a number of teeth design into with lubricated different structure of gear tooth number, guarantee by the gear tooth of lubricating gear can with produce oil tooth and the contact in turn of nanometer sponge tooth, guarantee lubricated effect. The utility model discloses only provide lubricating oil and use, do not participate in power transmission, the gear body adopts non-metallic material, even the slight piece that produces in the use can not cause the injury to former drive gear's transmission yet.

Compared with the common spray lubricating oil, the utility model has good lubricating effect and can realize the oil saving of more than 60 percent; the product basically realizes fault-free operation within 3-6 months, and ensures that the enterprise equipment does not need maintenance within the period of overhaul and maintenance; the gear is simple and convenient to replace, and the whole gear is replaced together without independent maintenance.

Detailed Description

Referring to fig. 1-3, a lubricating gear comprises a gear body, wherein the gear body is provided with an axially extending central hole 6 and a plurality of gear teeth distributed circumferentially, the gear teeth are divided into oil outlet teeth 1 with oil outlets and oil absorption teeth 2 attached with oil absorption cotton, and the oil absorption cotton 5 is nano sponge; the oil outlet teeth 1 and the oil absorption teeth 2 are circumferentially arranged on the gear body at intervals, a plurality of oil outlets 7 are arranged on the meshing surface on one side of the oil outlet teeth 1, an oil guide channel 3 is communicated between the oil outlets 7 and the central hole, and an extruded oil valve 4 is arranged at the oil outlets 7.

The lubricating gear may be mounted on a rotary shaft or the like through a center hole 6, and lubricating oil may be fed into the center hole 6 through the rotary shaft or the like, the lubricating oil may enter the oil guide passage 3 and finally be delivered to the oil outlet 7, and the lubricating oil discharged from the oil outlet 3 may flow onto the corresponding tooth surface. The extrusion oil valve 4 is in threaded connection with an oil outlet, the extrusion oil valve 4 comprises a stud 41 with threads, a front wide stepped hole and a rear narrow stepped hole are arranged in the middle of the stud 41, a steel ball 42 and a spring 43 are arranged at the wide diameter of the stepped hole, the outer diameter of the steel ball 42 is larger than a diameter locking port at the front end of the stepped hole, two mounting holes 44 are formed in the front end face of the stud 41, an annular groove is formed in the outer side face of the front end of the stud 41, and a sealing gasket 45 is embedded in the annular groove.

The oil absorption cotton 5 is attached to the meshing surfaces on the two sides of the oil absorption teeth. The oil absorption cotton 5 and the oil outlet are positioned on the same side of the gear teeth.

When the two gears are in meshing transmission, when the two gears are meshed with a meshing surface with an oil outlet 7, a steel ball 42 in the oil valve 4 is extruded, the steel ball 42 extrudes a spring 43, the oil outlet is opened, and lubricating oil in an oil guide channel flows out to the oil outlet to lubricate the whole tooth surface.
